The Intel® MPI Library includes two utilities for improving MPI performance. The Automatic Tuning utility allows you to tune runtime parameters to match your system and applications. The Intel® Trace Analyzer and Collector allows you to instrument and profile your MPI programs to improve parallelism. I will be presenting a webinar on December 12 discussing how to use these capabilities to improve your MPI application's performance.
